I have a number of used '69 wiper motor assemblies and some have the part number 5045572 stamped on the end of the motor casing, and some have it on a silver foil sticker/label; the casing end just has Type E 12V on those with the label. The foil stickers are from later 69 production, judging by the julian date code on the stickers I have. The stamped casings don't appear to have a date code.
Would it be correct to think that motor assemblies changed over at some point from earlier motors having the assembly part number stamped, to later motors having it printed on a foil sticker, and if so, at what point in 69 production did the change occur? Was there a difference too between NOR and LOS/VN produced cars?

I can only provide one data point for a data base.  
My original 09C (*Sept 17, 1969) Z28 / RS  has the silver pn sticker and date code on the wiper motor.  
photo is attached.   Sticker PN:  5045605,    also has '227   9   6   A' printed on it.
'227   9  ' might be the Julian date and year (15 Aug '69), which would correspond well to my mid Sept built car, but that's just a guess on my part.
If you begin a data collection on this, I'd suggest collecting the car build date, RS or not, PN on the sticker, along with the other data, and maybe we can begin to make sense of the information?   eg.

Car build date        RS?       sticker PN?       Stamped PN?                 Other codes

       09C                     Y         5045605                   N                      227      9     6      A

Thanks Gary,
Yes, the date code (as I understand it) is:
Assembly Part #
Julian Date (Day)__Year__Factory Line__Shift Code

So in your case, the part # is for an RS wiper assembly * (mine, 5045572, is standard assembly for non-RS car).
Assembled 227th Day of 1969 on line # 6, 'A' shift (Day).

Just trying to determine if there was a changeover date, with a view to putting the correct one on my 04A car.

* (Before someone mentions it, I believe that a non-RS car could have had the #605 assembly if it had the headlamp washer option, but that was rare).

Perhaps we can start off some data point collection, following on from Gary's chart?
If we can add the sticker details here, it may start to indicate a date range for sticker use....
Gary - I also added in column for final assembly plant.
Car build date    NOR/LOS      RS?       sticker PN?       Stamped PN?                 Other codes

       09C                                   Y         5045605                   N                      227      9     6      A
       ??                                     N         5045572                   N                      282      9     6      B

Gary,

You might add another field to the features poll - I have a RS/5605 that it stamped, foil tagged and has a very faint yellow ink/paint stamp with the part number on the side of the case. Only one like it I have ever seen - I have 4 or 5 of them, but this is the only one with an original enough finish to show the rubber stamped part number. I'll try to get a pic of it during day light so it will show up -

Regards,
Steve

Steve,

Add your data to the listing for all your motors, and add the additional column.   easier now than when the list is larger *G*

Steve, it would be great if you can add your details to the list above; since your wiper motor has both a stamp and a sticker, it may be from around the time of the changeover - i.e. using up stocks of stamped casings at the same time the stickers were being added once the motors were assembled.
Cheers, Tim

Updating the Windshield Wiper Motor data list with CROB's info..  since he didn't do it himself..  Smiley
(and I noticed the Julian date code on his motor is about a month prior to car build date, and stickers were used as early as May)

Please add your information to the bottom of the chart and repost for the data point collection....

Car build date    NOR/LOS      RS?       sticker PN?       Stamped PN?                 Other codes

       09C              NOR              Y         5045605                   N                      227      9     6      A
       ??                                     N         5045572                   N                      282      9     6      B
       06A               NOR             N         5045572                   N                      134      9     6      B

Steve, are you sure that wiper motor is original to the car, as a julian date of 079 and an 01D trim tag build date don't align? If the julian date on the motor assembly is model year, not calendar year, that doesn't seem to match well with the other data so far.....
The 'B F' at the end of the sticker throw the previous theory of factory line number and shift code a curve ball too....
Anyone have some ideas Huh

Sign of over maturity - the inability to proof read posts. Never seen a Pace Car built in January ? I haven't either - in my struggle to copy and paste the table, I entered the wrong date code twice. It is an 03D car, my X77 in an 01C: somehow I married the two. I'll have to dig out the X77's motor - if I remember correctly (again, tough at my advanced age), it is a stamped car, no tag. We'll see -

Thanks for catching me sleeping -

Regards,
Steve

Is there a date code on the early one that don't have a sticker?  I have a 12B RS that I can't see a date code.
